"To our knowledge, the Justice Department has never 'compromised' Ms. Atkisson's computers, or otherwise sought any information from or concerning any telephone, computer, or other media device she may own or use," a Justice Department spokesman told Business Insider Tuesday night.

Attkisson told WPHT Philadelphia host Chris Stigall that her computers have been compromised for "quite a long time."

"I don't know details of his — I only know what I've read," Attkisson said. "But I think there could be some relationship between these types of things and what's happened to me."

CBS spokesperson Sonya McNair told Business Insider that the network is "investigating the matter."

Attkisson, an Emmy Award-winning investigative reporter, has long reported on some of the issues most sensitive to the Obama administration, including the so-called "Fast and Furious" gun-walking scandal, the administration's spending on green energy, and, as of late, Benghazi.
